Not in an at-risk area
CM13 1UN has no properties in any Environment Agency recorded flood-risk band. That is good news — but it is area-level and never proof a place cannot flood (surface-water and sewer flooding are assessed separately). See the at-risk postcodes in CM13 or get the full picture below.
Because 3 recorded floods nearby; 216 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around CM13 1UN. The small panels are illustrative previews of the report's per-layer map views — the full report draws each layer for real, plus recorded extents, defences and a building picker on an interactive map.
Warnings cover flood areas, not individual addresses.
